Monday Mutant 71: Adam's Grapple

Draw a single loop that connects the grid cells. The loop may only travel horizontally or vertically, and never diagonally (so all turns are of 90 degrees). The loop may only turn at the centers of grid cells, and may not cross itself or branch off. The loop must pass through and turn in every numbered cell, and each number represents the length of each of the two line segments which meet at that cell.

With apologies to Adam Wood.
